Answer:

Step-by-step explanation:
we know that
The general equation of a quadratic function in factored form is equal to

where
a is a coefficient of the leading term
x_1 and x_2 are the roots
we have

substitute

Applying the distributive property convert to expanded form




therefore

A.)The equation is 24 + 8=32. Twice of the amount of 24 is 6 times the amount of 8. 24 x 2= 48. 48/6=8.
B.) X +Y=32 and 2x=6y
Answer:
(3x - 2)(x - 5)
Step-by-step explanation:
3x² - 17a + 10
(3x - 2)(x - 5)
3x · x = 3x²
3x · -5 = -15x
-2 · x = -2x
-2 · -5 = 10
